Cannot safely remove USB memory and USB DISK

kujirasan · 09-25-2011, 12:08 AM

Hi there, I am using Debian Squeeze with KDE , I cannot safely remove USB memory stick and disks, and get the following message: Device Not Mounted by HAL,
however; when I start the computer with USB connected, I can safely remove them, but if I insert/connect, it does not allow for safe removal, as well cannot copy or past to them!
Any advice be appreciated

Some issue with hotplug maybe.

Boot to that live cd and see if you can replicate the issue on the live cd.

i think is you cannot copy paste to them then they are not mounted and you can remove them just fine.
simply open a terminal window su to root then do
tail -f /var/log/messages
then plugin the usb stick
observe the output and get the device name for me it's always /dev/sdb1 or something like that
then do in another root terminal
mount /dev/sdb1 /media/flash

use whatever mount point you like /media/flash is just what i use

then when you are done
umount /dev/sdb1

then just yank the think when the umount returns

Hi, I thik I have worked out the problem, I installed both Gnome and KDE on the computer, and seems they clash, The whole thing work in Gnome and but not KDE.
There is UDEV and HAl, just wonder which should be used, and which one should be removed, if they meant to do the same job.

Hi Jefro, here we have Debian Squeeze 64Bit, and Fedora 14 , 64 Bit, the Debian one causes lot of problems, The Debian one has both Gnome and KDE, while Fedora has only KDE, but Generally KDE is used.So testing on live CD is not an issue , all USB devices work normally.
